  <h1 id="模块和包-包列表入口"><a href="#模块和包-包列表入口" class="headerlink" title="模块和包(包列表入口)"></a>模块和包<a href="package_list.md">(包列表入口)</a></h1><p>在python中，模块是个核心概念</p>
<p>每一个python程序都是由内建函数模块和外部模块组成的，就好比一个个不同的工具包，里面包含了不同功能的工具</p>
<p>每次要使用工具包(模块)时，必须先找到工具包(模块名)，再取其中你所需要的工具(函数)进行使用</p>
<p>每一个<strong>py</strong>模块和<strong>pyc</strong>文件都可以被当成一个模块来用，在模块中定义的 <strong><code>函数</code>，<code>全局变量</code></strong> 都可以被当作模块的参数进行调用</p>
<!-- 使用方法

<ul>
<li><p>读取顺序：</p>
<p>  .&#x2F; <code>当前目录</code></p>
<p>  %path% <code>系统环境目录</code></p>
</li>
</ul>
<h3 id="别名"><a href="#别名" class="headerlink" title="别名"></a>别名</h3><figure class="highlight python"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">import</span> 旧模块名 <span class="keyword">as</span> 新模块名 <span class="comment"># 符合大驼峰</span></span><br></pre></td></tr></table></figure>

<ul>
<li><p>注意: 模块别名的使用情况</p>
<p>  有同名模块的时候, 后导入的模块会覆盖之前的模块, 这时候就可以对其进行重命名</p>
<p>  模块名太长, 太复杂时, 可以利用别名来简化模块名</p>
</li>
</ul>
<h3 id="局部导入"><a href="#局部导入" class="headerlink" title="局部导入"></a>局部导入</h3><figure class="highlight python"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">from</span> 模块名 <span class="keyword">import</span> 某个工具</span><br></pre></td></tr></table></figure>

<ul>
<li>注意:<br>  局部导入后, 可以不用<code>别名.</code>的方式来调用工具, 直接使用即可<br>  (这也就产生了<code>from module import *</code>的方式来简化模块的使用)</li>
</ul>
<h3 id="name-属性"><a href="#name-属性" class="headerlink" title="__name__属性"></a><code>__name__</code>属性</h3><p><code>__name__</code>就是在兼顾文件开发和测试性的一个内置属性</p>
<p>打开一个python文件，输入</p>
<figure class="highlight python"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="built_in">print</span>(__name__)</span><br></pre></td></tr></table></figure>

<p>就会返回</p>
<figure class="highlight python"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">__main__</span><br></pre></td></tr></table></figure>

<p>这是因为你在直接运行某个python文件的时候，解释器会把该文件当作主程序，并且赋予这个文件一个<code>__main__</code>属性</p>
<ul>
<li><p>原因</p>
<p>  在导入一个python文件的时候，解释器会把文件主程序完全运行一遍，这就导致如果你之前保留的测试代码，也会重新运行</p>
</li>
</ul>
<p>但如果你不想运行测试代码，又想保留他们，就把主程序除定义以外的运行代码全部放到<strong>属性名称判断</strong>下面</p>
<figure class="highlight python"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">if</span> __name__ = <span class="string">&#x27;__main__&#x27;</span>:</span><br><span class="line">    <span class="keyword">pass</span></span><br></pre></td></tr></table></figure>

<p>导入文件时解释器会给导入文件的<code>__name__</code>属性定义为<code>导入文件本身的名称</code>, 这样最后结尾的<code>if</code>就为<code>False</code>，其后方的代码就不会被解释运行</p>
<h2 id="包"><a href="#包" class="headerlink" title="包"></a>包</h2><p>包，就是很多个模块的组合一个，包不是一个文件，而是一个模块的目录</p>
<p>包的文件结构：以一个package包为例</p>
<ul>
<li><p>&#x2F;package</p>
<p>  <code>__init__.py</code><br>  <code>module_1.py</code><br>  <code>module_2.py</code><br>  <code>module_n.py</code><br>  <code>modules_rquire.py</code></p>
</li>
</ul>
<p>其中有个很特殊的文件<code>__init__.py</code></p>
<p>其内容如下：</p>
<figure class="highlight python"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line"><span class="comment"># 从 当前目录 导入 模块_n</span></span><br><span class="line"><span class="keyword">from</span> . <span class="keyword">import</span> module_1</span><br><span class="line"><span class="keyword">from</span> . <span class="keyword">import</span> module_2</span><br><span class="line"><span class="keyword">from</span> . <span class="keyword">import</span> module_n</span><br></pre></td></tr></table></figure>

<p>可以看作是包的初始化文件，其中的module可以看作是导入后直接能被执行的模块文件</p>
<p>modules_require可以看作是模块的小依赖</p>
<p>只有在<code>__init__.py</code>中有的模块才能用包进行导入</p>
<h3 id="制作和发布包"><a href="#制作和发布包" class="headerlink" title="制作和发布包"></a>制作和发布包</h3><p>先创建一个<code>setup.py</code></p>
